How would you set 2 "child Of" constraints on the same object?
I was just looking for an answer, and I've actually found a workaround myself.
Create a new armature for the hat, scale the root bone and make it small, then parent the hat to your new armature. You will have 2 armature sets and you can use &quot;Child Of&quot; again. If you changed the influence slider, you may have not the desired influence movements, so what worked for me was to subtract the first armature influence with the new one.
